. Application led December 21, 1910. Serial No. 558,521.

To all cdhomt may concern Be it known that I, THEODORE ABTMEYER, a citizen l.ofthe United States, and a resident of Wilkin'sburg, in the county of Allegheny and State of Pennsylvania., have inand vuseful Improvement '-in Percolating Devices, of 'which the follovv.

ing is aA specification.

My invention relates to electrically heated l ponent parts thereof, except the'eleetric pense.. Furthermore,

heater, are preferably made of glass and are.`v

readily removable .for the purpose of clean'- ing. I tire pefcolating process is visible and may be governed according to its progress and conditions.

1n the prior art,.it has been customaryv practice to construct percolating apparatus in which the percolating action was continuous; that is, the liquid. passed same cycle of operation until the Whole body was sufficiently saturated. This process -involved a considerable length Vof time and eX- pense, which Wasprohibitive if only a small amount offcodee Was desired.

lAccording to my easily placed in position to receive 4the liq'- uid which percolates through the coifee grounds, or the like; Thus,`the coffee is 'collected after having passed butonce through the grounds and it is evident that a small quantity of coffee may be made in a very short time and at a relatively small exinasmuch asthe inner receptacle is readily removable, it is a matter of case to adapt my percolator to the usual mode of' operation, whereby large quantities of coffee may be made. A very useful, adaptable, and sanitary device is t is'evldent, therefore, that the`en through the invention, I provide a removable inner receptacle -that maybe therefore provided which is not only inex- .pensi-ve in construction but' is economi'cl'to operate and maintain.

The single figure ofthe accompanying drawing is a view, partially in sectionla'ncl partially in -elevation, of a device constructn ed in accordance with. my invention.

Referring to the drawing in detail, lthe'de- I vice herein shown comprisesa liquidonf taining vessel 1, a cover 2,an incased electric heater 3, a fountain tube 4, a perce lator pump 5,' an innerreceptacle, fand a percolator cup 7.' j j fj TheV liquid-containing'vessel 1 is preferablv a. glass pitcherhaving a handle 8 and a plurality ofAV legs 8-, `but any other suitable receptaclemalof 'course,be emf ployed. 'The cover 2, wl1ich-is 'also preferably4 constructed ofglass, embodies a dome or chamber -9 and fits tightly on to the tup# per portion ofthe pitcher 1.

The electric heater 3grests`up'on thebot.

tom l0 of the pitcher'l and is provided with a protecting tube 11 which projectsI through an opening 12 in the upper-edge .ofthe ivi;

pitcher 4land terminates ina Suitableplijml l:

dle 13', Within which the necessarycircuit connectlons are made.

eration of the device herein shown, I pre1' fer that its construction conform to that shown and described in detail in ac opendfA ing application, Serial No.l 595,619, filed' 1910, by E. Rose and asf 80., Althoughi the lheater 5 3 forms no part of my inventiom-exceptasf it'performs la necessary function in the ,opff

signed to the Westinghouse'lectric & Manufacturing Company. Any other electric heater may, of course, be employed.

The fountain tube 4, which is centrally4 disposed upon the heaterunit 3, vand may be rigidly 'attached thereto, projects up vnardly into the dome or chamber 9 and is provided, near its lower end, with the percolator pump 5, which may beef any of the ordinary forms of construction.

Thelinner receptacle 6 is preferably' constructed of. glass and embodies a nose 11 and a centrally located integral tubular 'member 15, through which Ithe' fountain tube 4 projects. ,The upper portion 16 of thetubular. member 15 is provided with a contracted opening, the edge 17 of which rests upon the top of the fountain tube 4: and

nolds the receptacle G in position. The per- :folaior @up ,7 may also he ot glass and is l `vided with a sieve or sereen 1S at its ooitom and sides,and with an .integral tuhtiiar member if) which similarly tits over 'l e Vfountain tuue t and the tubular member "the, ytubular member it) is provided with a contrat-,tedupper edge it) by means of uziieh the retaining eup suitably susA ,ded in position. Assuming the various parts ot the deyife t in the position. shown, the operation her of is as t'olionjs: `dhen eleetrie energy is supplied to the heater a a portion ot.' the iiduid :il eontaiued within the piteher ll is intermittently projet-ed upwardly through thefountain tuliel inthe usual manner. As the liquid is thus 'toreed up through the t'uhe -i it is eaught in the eup i' and pereolates through the eot'iee grounds 22 eo'ntained therein? after whieh it eolleeted in the inner rereptaele (S until the desired 1| iantity is lit'ainsnl, y`hus ity is evident that a small amount o1 eotlee may he made in a eomparatively short time'and at a reasonable expense as it is uniuwessary to inasmuch malte, aufY moreI than is aetually desired. titer the proeess has eontinued a sutiieienl Linie tio produce the amount ot otl'ee desired,y Ehe operation is diseontinued and the heater mit,y inner reeeptaele and other associated ia if are removed bodily from the pitoher by inea.. otE the handle 1I-l, whence the cot'- ee may he dispensed through the nose 1l. n ease a large amount otl eoti'en is desired, e inner receptacle may he readily removed and the remaining parts replaeed within the teher i, after whieh the process may he oja yinnerL `in they usual manner.

l ii'ious modifi 'ations may he made in the tural details and in the arrangement leation ot parts without departing "ie :spiritaiiil seope, of my inyention. desire that, only sueh limitations shall nnposedas are indicated in th appended i' ne im as my invention:
